IPC: C08F2/18
Filed: 2000-03-07
Abstract: PROBLEM TO BE SOLVED: To prepare a vinyl chloride-based polymer with a high productivity without generating coarse particle size and abnormal phase transition attributable to the weight ratio of an aqueous medium and a vinyl chloride-based monomer in a polymerization reactor in a charging period and abnormal polymerization and insufficient heat removal due to the high initial polymerization rate in a method to shorten the production cycle of a vinyl chloride- based polymer where the aqueous medium and the vinyl chloride monomer are charged simultaneously.

Title: Device for shutting off air into pouring stream between tundish and mold
Inventor: ITO SATOSHI
IPC: B22D11/106
Filed: 2000-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a device for shutting off air into the pouring stream between a tundish and a mold in a continuous casting, with which the good sealness can efficiently be obtained without obstructing the work in the continuous casting. SOLUTION: The device for shutting off air into the pouring stream 7 by being disposed between the tundish 8 and the mold 6, has an air shutting-off cylinder for surrounding the pouring stream 7, and in the air shutting-off cylinder, a gas ejecting hole 5 for sealing, ejecting sealing gas toward the upper part of the pouring stream, is arranged. When the sealing gas is injected toward the upper part of the pouring stream with this device, the injected sealing gas descends along the pouring stream, accompanied by the pouring stream and the pouring stream is always surrounded and thus, oxygen concentration in the atmosphere of the whole pouring stream is reduced. As a result, the oxygen concentration in the atmosphere drawn into molten steel at the molten steel dropping position, is restrained to the low level and the oxidation of the molten steel can be prevented.

Title: Staff for level using seal for checking
Inventor: OGURA RIICHI
IPC: G01C15/06
Filed: 2000-02-02
Abstract: PROBLEM TO BE SOLVED: To enable quick checking for the zero point of a staff holding it stably with both hands when the height of the top surface of concrete or the like is secured by a leveling machine overcoming the difficulty in holding the staff with one hand as required in keeping it vertical and moreover, floating in the concrete during the checking. SOLUTION: A seal 6 is mounted at a position of 0 mm of a staff 1 with a magnet 4. The staff 1 is held with both hands with one hand at the part 8 near the point of 0 mm of the staff 1 and a rear part 9 of the seal 6 is pressed with a little finger of the hand, a foot or the like to allow sealing quickly on a measuring stick 7. The use of both the hands enables holding of the staff stably. The shortcoming is that the erection of the staff is confined only to one fixed direction because of printing by the seal, which determines the position of the leveling machine accordingly, eventually hindering smooth handing of work. To make up for the shortcoming, the cross section of the staff 1 is made round to allow installing of the leveling machine in any direction.  In the case of automatic leveling, a receiver 10 is made round in shape thereby eliminating the need for making the staff 1 round.

Title: High-speed tornado producing method and apparatus, and its utilization apparatus
Inventor: YONEDO KAZUMASA
IPC: F24F7/06
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a high-speed tornado producing method and an apparatus, and its utilization apparatus in which a high-speed tornado is produced with ease without relying upon a large-amount air high-pressure air fan, and characteristics of the high-speed tornado are utilized. SOLUTION: Gas is turned in a predetermined direction into a turning air stream 9, and the gas is sucked from at least one direction in a rotation axis direction of the turning air stream 9 to produce a tornado 10. Sucking of the gas thereupon is achieved by a high-pressure suction inlet 1 where sucked pressure is made higher and a low-pressure suction inlet 2 where pressure is made lower than the suction pressure at the high-pressure suction inlet 1.  An air velocity at an outer diameter of a core portion 11 of the tornado 10 produced as such is speeded up, and the core portion 11 of the high-speed tornado is sucked toward the high-pressure suction inlet 1 and a tornado portion 12 other than the core portion is sucked toward the low-pressure suction inlet 2, so that an air velocity at the outer diameter of the core portion 11 of the tornado 10 can be increased to the limit of suction pressure, and hence contaminants diffusing at a high speed can be captured by the high-speed tornado 10.

Title: Method for embedding information in picture and method for extracting the same information
Inventor: YOSHIURA YUTAKA
IPC: H04N1/387
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To easily embed multi-bit information such as a digital signature in a small sized picture (graphic mark) using an electronic watermark. SOLUTION: An image is converted into frequency expression, and the value of the amplitude or phase of a cosine wave is displaced by bits to be embedded. That is, the coefficient values of the preliminarily decided elements of a DCT coefficient matrix 42 representing a picture block (8×8 pixels) 41 to be embedded out of a whole picture 43 are displaced by bits to be embedded. Also, not only the bits of information to be embedded but also the bits of the result of the rearray, conversion, or arithmetic operation of the bits can be obtained as the embed information to be displaced. Also, the bits to be displaced can be decided on the basis of the value of the amplitude and phase of another cosine waver or the value of the amplitude and phase of the cosine wave.

Title: Network supervisory method
Inventor: MIMURA ITARU
IPC: H04L12/70
Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a network supervisory method that can collect statistic supervisory information by each communication flow at a low cost. SOLUTION: A packet switching apparatus of this invention detects a communication flow and also detects statistic supervisory information such as the number of passing packets, the number of aborted packets, a packet arrival time and a packet transmission time with respect to the communication flow. The packet switching apparatus collects the statistic supervisory information with respect to the communication flow during the communication flow continues. When the packet switching apparatus conducts a packet relay function, the packet switch transits the collected statistic supervisory information to a downstream packet switching apparatus and when the downstream packet switching apparatus is an edge node, the packet switching apparatus summarizes received statistic supervisory information and transmits the summarized information to a network management unit.  Thus, a user terminal can considerably reduce a communication amount of the collected supervisory information from two edge packet switches. Furthermore, the user terminal can collect the supervisory information by each flow.

SOLUTION: Whether or not a value added starter driving time (t) of this time to a starter driving time integral value T up to the last time is not less than a time judging value (520 thousand sec) is judged in a Step 410. Here, when judged as Yes, the Step advances to a Step 430. While, when judged as No, the Step advances to a Step 420. Whether or not a value added a starter driving frequency (n) of this time to a starter driving frequency integral value N up to the last time is not less than a frequency judging value (130 thousand times) is judged in the Step 420. Here, when judged as Yes, the Step advances to the Step 430. While, when judged as No, the Step advances to the Step 410.  In the Step 430, the engine starting control is stopped (engine stopping control is also stopped) by being regarded as satisfying a condition for finishing the engine starting control (accordingly, the engine stopping control as well), and this processing is finished once.
